diode mode on L9580 is 0.333 L9080 also 0.333 (U9580 removed)

I found the short to be on PPBUS_G3H_SSD1_SNS. Removed U9580 and the short is gone. Does this mean dead SSD?

Hi, got 820-01041 board that doesnt boot. Its pulling 5v 0amps from all ports. Diode mode to ground on F7001 gave me 0.09. Removed F7001/F7002. Resistance to ground on system side is 24.4 ohms. On visual inspection i get nothing.

Reference codes: PFM006 and PPN001

Diagnostic mode says theres an error with the SMC

Hi, got an 820-00165 that did not turn on and had liquid damage in the U1930 area, components replaced and now it boots but fan goes full throttle after Apple logo loading bar is more than 70% and into the OS. Chant be changed with any fan control software. All temperature sensors are below 40...

SPI Bus Termination resistors all are OK and their traces. J6100 is cleaned, no change.

No change with clean ME

No history. PLT_RESET_L is 3.3v stable Do you clean clean ME for this board? Thanks

I have a 820-00165 board. When connecting the charger it has green light and the fans spins. The LCD stays black. Keyboard doesnt light and neither does the caps lock key light. CPU gets warm. SCM reset works but PRAM reset doesnt. It also doesnt give image with everything disconnected but the...

all seem good and have good connections but RT365 and RT366 are measuring 9.3k (should be 47k). SPI_IPD_MOSI is 0.284 (0.330 on openboard reference).

IPD_TOUCH_RESET_CONN_L = 2.96v IPD_MCU_RESET_CONN_L = 2.96v PP1V8_AON = 1.8v IPD_MCU_RESET_L = 1.8v IPD_TOUCH_RESET_L = 1.8v

No sorry, i had a typing error. IPD_TOUCH_CLK_CONN is 0.419

Diode mode measurements are ok: I2C_KBD_SCL 0l I2C_KBD_SDA 0l I2C_SMC_IPD_SCL_CONN 0.500 I2C_SMC_IPD_SDA_CONN 0.500 IPD_MCU_INT_CONN_L 0.474 IPD_MCU_RESET_CONN_L 0.679 IPD_MTP_FUNC_1_CONN 0.592 IPD_SYS_AWAKE_CONN 0.431 IPD_TOUCH_CLK_CONN 0.000 IPD_TOUCH_INT_CONN_L 0.730...

UT360 was shorted. After replacing i get 3.3v on PP3V3_S2SW_IPD_F. PP5V_S2_IPD_F, IPD_LID_OPEN_1V8, PPBUS_AONSW_IPD_F are present. (measured on JT400) Still no keyboard or TP Tried different TP flex cable, no change.
